10 Questions
What are the two main categories of water sources?
Groundwater and surface water
What is an aquifer?
An underground water reservoir made of permeable rock
What are some examples of surface water?
Streams and rivers
What is aquifer depletion?
When more water is pumped from the aquifer than is allowed to recharge
What can happen to the land if too much groundwater is pumped from the aquifer?
The land may subside
What are the dangers associated with land subsidence?
Land subsidence may create dangerous sinkholes, which are cavities in the ground that are funnel shaped and open to the sky.
What caused the Leaning Tower of Pisa to sink and tilt?
The Leaning Tower of Pisa sank and tilted due to the compaction of unstable ground caused by extreme groundwater pumping.
What are some consequences of aquifer depletion?
Some consequences of aquifer depletion include less water reaching streams, rivers, and lakes, dried up wells, a lowered water table, and saltwater entering the groundwater supply.
How have surface waters, such as rivers and lakes, been affected by human activities?
Surface waters, like rivers and lakes, have been overdrawn and diverted for human needs, leading to reduced water flow, dried-up areas, and negative impacts on ecosystems.
How does irrigation contribute to soil salinization?
Irrigation leads to soil salinization by adding dissolved salts to the soil through the evaporation of water, as well as the application of fertilizers, which exacerbate the problem.
